' Be it known that l, Minets l. BROCK, a citizen of the United States, residing at llfayne, in the county of Delaware, State of Pennsylvania. have invented a new and use- `ful Wheel-Hub, of which the following is a specification.

The invention relates to improvements in hubs 'for vehicle wheels. The object is to provide improved means for securing the removable to the .ifixedhub element to provide pom'tive engagementl locking' over such lar e surfaces as to minimize wear and to provi e continuous coincidental compensation therefor.

lhe invention comprises means for positively preventing relative rotative and longi tudinal movement between said elements and also means 'for taking up wear between said two elements continuously and coincidently.

Referring to the drawings, which illustrate merely by way of example, suitable embodiment oir my invention* lligure l is a front elevation of an improved hub eomprising my invention.

Fig. 2 is a side elevation of same. Fig a section on line 3;-3 of Fig. 1,` on an enlarged saale, A

L is a section on line il-1l of liig. 3. lligs, and o are ibagmentary views in perspective, showing the interloelring mean hetween said hub elements.

Similar numerals refer to similar parts throughout the severalviews.

The lined hub elenienm'l is shown as beingoi true cylindrical formation and is provided withy the conical ring member 8 secured to' the flange 9 by the bolt i0 which also @cures 'if e brake drum ll. As stated this inclined enlargement 8 shown in the drawings as a separate or an additional piece secured to the. .lined huh il llt is obvious however that it may be formed integral therewith. The

surface oi the inclined periphery of 8 is provided with longitudinally and inwardly. (or outwardly) extending tapered formations i2, The removable hub element 13 is shown 'with a cylindrical formation longitudinally,

and provided .withthe portion lll of substantially corresponding inclination with f or the el? eatenmf'on 8 ofthe fixed hub. rl`his portion ll of the removable hub element is provided with longitudinally and inwardly (or outwardly) extending tapered formations'l which register and co,

operate with the similarly extending tapered formations '12. As shown in F ig. 3 sucient room or .space is provided between the flangesla and 16 whenthe extensions il and will be obvious that the cooperating longitudinally and inwardly or outwardly extending tapered formations on Ithe fixed and movablehub elementsmay be reversed as to the direction of taper.

' lt will further be obvious that the object of my invention ma be obtained in accordance-with the principle illustrated, not only bythe use of tapered formations of curvedl cross-section, but also by formations oi any other cross-section, so that atleast one surface convergestoward one or more of the other surfaces,` and provides continuous eo-4 incidental com ensation for wear and the l formations oft e two hub elements coperate with each other; 'and it willbe obvious further that the taperedsurface between the inwardly or outwardly extending formations may be used as a furthermeans of lock- -ing (but not by engagement) the twohub elements, but is not essential to this invention. i i n .'lligs. 5 and 6 show alternative arrangements which are in many respects substan tial equivalents. 'An essential feature of the invention'is that the cooperating conical or tapered feature means for taking up wear is operatively Aand essentially combined with the feature' of positively locking against relative rotation of the two hub elements.,

lVhat l claim isz-- il fixed hub element comprising a substam tially cylindrical body., a relatively short 'roo tapering shell surrounding and seoured to tapering recesses for coperating with the said cylindrical body und provided with a tfapering progeotions.
